Exceeding power output under internatinoal agreements

 * * The Marathon, Florda MW trasmitter used by IBB operates at 100 kw, breaking the US treaty obligation to only transmit at MW powers no greater than 50 kw

IBB claims on their website:


 * "Radio Marti: Marathon Key, Florida -- Facilities include a directional four-tower antenna array and two 50 kilowatt (kW) transmitters operating on 1180 kHz (medium wave) as well as a power combiner system that allows the station to transmit a more powerful 100 kW signal during daylight hours. The broadcast signal is sent by satellite from Miami to Marathon Key."

Okay, according to ITU-R's "TERRESTRIAL BROADCASTING PLANS IN LF/MF/HF/VHF/UHF BANDS" the MF band (defined as 526.5-1 606.5 kHz, 525-1605 kHz, and 1605-1705 kHz) is subject to the following restrictions, per ITU-R publication RJ88:


 * 2.2 Regional Agreement on MF Broadcasting, Region 2, Rio de Janeiro, 1981


 * "– class A stations, covering large areas, are protected for their ground-wave and sky-wave service; their power shall not exceed 100 kW daytime and 50 kW night-time except stations originally recorded with higher power, which however can not be increased;"

So if they transmit at 100kw during the day, and 50kw during the night, then IBB IS adhering to ITU-R regulations, no?

New Director of the International Broadcasting Bureau
I am an employee at the International Broadcasting Bureau. A new director of the International Broadcasting Bureau (IBB) was recently appointed, and I updated the Wikipedia article to reflect our change in leadership.

I also made a minor update to the introductory paragraph to reflect that IBB is an entity within the Broadcasting Board of Governors (BBG), a U.S. independent agency, rather than an agency in itself.
